- Global consumer demand for polypropylene staple fiber [8/18/2020]
- About 952,000 tons were consumed in 2018, accounting for 11% of global nonwovens consumption. Although the use of polypropylene staple fiber in the disposable market has declined, especially the demand for dry-laid thermal bonding covering materials (only partially compensated by the use of air-laid), this fiber is in the durable nonwoven market Continues to grow. Most of the durable end markets for polypropylene are needlepunch durables. The main markets where needle-punched polypropylene is used include geotextiles, automotive parts, coating substrates, indoor/outdoor carpets, blankets, upholstered furniture and mattresses.The forecast of global demand for polypropylene staple fiber in 2023 is 1.1 million tons.From this point of view, the market consumer demand for polypropylene staple fiber is generally on the rise, and the potential is huge.......
- 4.17 billion yuan in cotton purchase funds let cotton farmers eat [8/11/2020]
- "Due to the better weather this year, the overall growth of cotton is better than last year. It may increase the income by 30-40 kg compared with last year, and it can reach 460-470 kg per mu." Adege Haoxi Village, Dalet Town, Bole City Said Zhang Ziyu, a big cotton farmer.On the afternoon of August 7, Zhang Ziyu, a big cotton grower in Adge Haoxi Village, Dalet Town, Bole City, was pouring 500 kilograms of diammonium phosphate into the water diversion tank of a motorized well, and using drip tape for his family’s 470 mu of land. Foliar fertilizer once.Since the beginning of spring this year, the temperature in Bole has been relatively high. After the cotton was planted, the growth and development were generally faster. The flowering period was about 10 days earlier than the same period in the previous year. The number of peaches in the high, medium and low yield fields were 3.2 and 2.2 respectively. There were 1.9, 1.8, and 0.7 more than previous years, and 2.4, 2.0, and 1.0 more than last year. It is worth mentioning that this year Zhang Ziyu chose the "order + deposit" planting model and signed a cotton planting contract with the cooperative Yadong Company. In March, he had received 500 yuan per mu, a total of more than 200,000 yuan in advance for seed cotton. Not only do not have to worry about the cotton sales after the autumn harvest this year, but also receive an early deposit. He confidently said: "Just grow good cotton, and don't worry about increasing income and getting rich." At present, the acquisition of new cotton is imminent. In order to meet the capital demand for the purchase of Bozhou New Cotton, the Agricultural Development Bank Bozhou Branch has prepared a fund of 4.17 billion yuan in advance to ensure the full supply of cotton purchase funds and effectively ensure that farmers "cotton is sold and money is paid." It is understood that the cotton planting area in Bozhou will be 2.19 million mu in 2020, which is an increase of 20,000 mu compared with last year. The estimated lint output is about 770,000 tons, and the purchase capital is about 4.2 billion yuan. Cotton credit is not only policy credit, but also people's livelihood credit, or poverty alleviation credit. It is of great responsibility and far-reaching significance to do this work well. The Agricultural Development Bank Bozhou Branch analyzed in advance, formulated targeted acquisition policies in conjunction with the supply of acquisition funds, implemented differentiated management for special circumstances, increased credit services for customers participating in cotton purchases, and fully satisfied customers in cotton purchases in a timely manner. Demand for credit.The Agricultural Development Bank Bozhou Branch fully fulfills its role as a policy bank, starts early, prepares early, and actively raises funds. It implements the party’s original aspiration and mission with practical actions, and earnestly achieves "money and other cotton", so that Bole cotton farmers can eat " Peace of mind".......

- my country's chemical fiber production accounts for 70%, but the textile recycling rate is less than 10 [7/28/2020]
- Where did your old clothes go? Did you throw them away at random or sent them to the clothing recycling bin? According to the China National Textile and Apparel Council's calculations, if all the waste textiles in our country can be recycled, it can save 24 million tons of crude oil a year. , Save nearly 1/3 of the cotton planting area and reduce 80 million tons of carbon dioxide emissions.The Chinese Academy of Engineering’s consulting and research project "Research on the Development Strategy of Waste Chemical Fiber Textile Resources Recycling Technology" was held recently in Beijing. The research report puts forward China’s report on the basis of in-depth combing and comparison of the status and development trends of waste chemical fiber textile resources at home and abroad. The key tasks of recycling of waste chemical fiber textile resources have clarified the development direction of the entire industry chain technology system. my country is the world's largest chemical fiber production and application country. In 2016, the total output of chemical fiber reached 49.44 million tons, accounting for 69.4% of the total global fiber. The total processing volume of textile fiber was 54.2 million tons, of which chemical fiber accounted for 84.23%, occupying a leading position. With the rapid development of the industry and the surge in consumption, the disposal of waste chemical fiber textiles also follows. It is estimated that by the end of the "13th Five-Year Plan" period, my country's waste chemical fiber textile production will reach nearly 200 million tons, but my country's textile recycling rate is less than 10%, which is a significant gap compared with developed countries. Waste chemical fiber textiles are treated as garbage for simple disposal such as landfill or incineration, which not only seriously pollutes the environment, but also causes a great waste of resources. Seeking regeneration and recycling has become an urgent need for the development of my country's textile industry.According to Jiang Shicheng, an academician of the Chinese Academy of Engineering, in order to promote the sound development and comprehensive upgrading of China's chemical fiber recycling industry, the Chinese Academy of Engineering established a consulting project "Research on the Development Strategy of Waste Chemical Fiber Textile Resource Recycling Technology" in 2017, led by an academician in the textile field, relying on Donghua Universities, and invited more than 40 people including experts from relevant universities and institutes and representative enterprises to participate in the research. It took more than a year to form a research report and academician recommendations."The recycling of chemical fiber is an important direction in the new era of the chemical fiber industry." Project Secretary-General Wang Huaping said that in the next 10 years, we must be guided by "zero abandonment, clean, low-carbon, high-efficiency, high-quality, and high-value" and take major technological projects as the starting point. , Supported by the construction of an independent innovation system combining “politics, production, learning, research, and application”, a national-level textile recycling research and engineering technology development platform has been established to enable China’s polyester, polyamide, polypropylene, and polyphenylene sulfide The recycling technology and innovation capabilities of other key chemical fiber varieties rank among the top in the world. On this basis, the project proposed key tasks. The first is the research on the basic scientific issues of the regeneration of waste chemical fiber materials; the second is the rapid identification and sorting technology of waste chemical fiber textiles; the third is the pretreatment and resource standardization of waste chemical fiber textiles; the fourth is the key technology of mechanical and physical regeneration and the industrialization upgrade; 5. It is the key technology and industrialization of physical and chemical regeneration; the sixth is the key technology and industrialization of chemical regeneration.

- What is the difference between polypropylene yarn and polyester yarn? [7/28/2020]
- What is the difference between polypropylene yarn and polyester yarn? Polypropylene is the trade name of polypropylene fiber. It is a fiber made from propylene as a raw material through polymerization and melt spinning. Polypropylene officially began industrial production in 1957 and is a rising star among synthetic fibers. Because polypropylene fiber has the advantages of simple production process, low product price, high strength and light relative density, polypropylene fiber has developed rapidly. Polypropylene is currently the fourth largest variety of synthetic fibers. The production of polypropylene fiber includes staple fiber, filament and split film fiber. Polypropylene film fiber is made by first making polypropylene into a film, and then stretching the film to split it into a network of fibrils. Polypropylene is widely used in the manufacture of industrial fabrics and non-woven fabrics. Such as carpets, industrial filter cloths, ropes, fishing nets, building reinforcements, oil-absorbing blankets and decorative cloths. For civilian use, polypropylene can be spun purely or blended with wool, cotton or viscose to make various clothing materials. In addition, polypropylene film fibers can be used as packaging materials. The main physical and chemical properties of polypropylene 1. Form The longitudinal surface of polypropylene is straight and smooth, and the cross section is round. 2. Density The biggest advantage of polypropylene fiber is its light texture. Its density is only 0.91g/cm3, which is the lightest variety among common chemical fibers. Therefore, polypropylene fiber of the same weight can obtain a higher coverage area than other fibers. 3. Strength and elongation Polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene fiber has good abrasion resistance. In addition, the wet strength of polypropylene is basically equal to the dry strength, so it is an ideal material for making fishing nets and cables. 4. Hygroscopicity and dyeability Polypropylene has very little hygroscopicity, almost no moisture absorption, and the moisture regain under general atmospheric conditions is close to zero. But it has a wicking effect and can transmit water vapor through the capillary in the fabric, but it does not have any absorption effect. The dyeability of polypropylene is poor and the chromatogram is incomplete, but the original solution coloring method can be used to make up for the deficiency. 5. Acid and alkali resistance Polypropylene fiber has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, polypropylene fiber has good resistance to acids and alkalis, so it is suitable for use as filter materials and packaging materials. 6. Light resistance, etc. Polypropylene fiber has poor light resistance, poor thermal stability, easy aging, and is not resistant to ironing. But it can improve its anti-aging performance by adding anti-aging agent during spinning. In addition, polypropylene has good electrical insulation, but it is easy to generate static electricity during processing.Polyester (1) What is polyester? Polyester is an important variety of synthetic fibers, and it is the trade name of polyester fiber in my country. It is a fiber-forming polymer made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reaction- -Polyethylene terephthalate (PET), a fiber made by spinning and post-processing. (2) What are the properties of polyester? 1. High strength. The short fiber strength is 2.6～5.7cN/dtex, and the high tenacity fiber is 5.6～8.0cN/dtex. Due to its low hygroscopicity, its wet strength and dry strength are basically the same. The impact strength is 4 times higher than nylon and 20 times higher than viscose fiber. 2. Good flexibility. The elasticity is close to that of wool, and it can almost completely recover when it stretches 5% to 6%. The wrinkle resistance is better than other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The modulus of elasticity is 22～141cN/dtex, which is 2～3 times higher than nylon. 3. Good heat resistance. 4. Good water absorption. 5. Good abrasion resistance. The abrasion resistance is second only to the best abrasion resistance nylon, better than other natural fibers and synthetic fibers. 6. Good light resistance. Lightfastness is second only to acrylic. 7. Corrosion resistance. It is resistant to bleaching agents, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. It is resistant to dilute alkali, not afraid of mildew, but hot alkali can make it decompose. 8. The dyeability is poor. (3) What are the major varieties of polyester? The broad categories of polyester include staple fibers, drawn yarns, textured yarns, decorative filaments, industrial filaments, and various differentiated fibers.......

- Small increase in local sales of polyester and viscose wool-like autumn fabrics [7/21/2020]
- Recently, as grey cloth stocks have rebounded again, corporate profit-sharing promotions have once again been put on the agenda. So far, many grey fabric companies are taking holidays due to few orders and operating losses. On July 16, the person in charge of a weaving company in Shaoxing said: Affected by the epidemic, the company could not receive orders and the production tasks were seriously insufficient. In order to reduce losses, the company decided to take a holiday from July 17 to August 16. month. It is understood that due to the small number of orders, more than 40% of enterprises in Zhejiang have suspended production and holiday, and some enterprises that have not been on holiday are also struggling. On July 16, the person in charge of a weaving factory in Zhejiang said that they had just received an order, but after calculating the cost, they lost an average of 0.20 yuan/meter. However, in order to maintain the normal production of the factory and ensure that workers are not lost, they can only accept it. under. The life of each factory this year is not easy, whether it is taking orders at a loss or taking a holiday to avoid risks, it is a helpless move. When will orders pick up? The industry generally lacks confidence. In the recent market, the sales of autumn wool-like fabrics made of T/R polyester and viscose blended yarn as the main raw material have increased slightly, and sales have also increased slightly compared with the previous period. On the first floor of Dongsheng Road Market in China Textile City and some large-scale business outlets on the first floor of United Market, autoclaved single-sided serge, double-sided serge and satin are filled with T/R65/35 yarn 30S, 32S and 40S as the main raw materials.

- Behind the crazy production of the chemical fiber industry chain [7/15/2020]
- Since the beginning of this year, due to the impact of the new crown epidemic, the global demand for textile and apparel has declined sharply, and the textile market has suffered a severe decline. The volume and price of products have fallen, and it is difficult for the weaving manufacturers to produce and sell, which has led to rising inventories. The lack of orders for weaving companies began to reduce the start of operation, and the demand for raw polyester yarns was further reduced.In the case of sluggish production and sales and increased inventories, polyester factories should start to reduce burden and reduce production. Recently, although 13 companies have implemented production limit pricing, in terms of scale, the volume of these 13 companies' production limit pricing is actually not large. Large factories like Hengli have not yet been added, and Shenghong has limited production. It is just polyester chips, the scale is relatively general, so the operation rate of polyester factories is still relatively stable."Inverted pyramid" industrial modelAs we all know, the textile industry chain is an "inverted pyramid" model. Terminal clothing largely determines the market price of the upstream market, and the market of terminal clothing can actually be seen from the dyeing factory. All fabrics must pass through the dyeing plant. Now, the start-up rate of the dyeing plant is only about 55%, which is the lowest operating rate in the industry chain.As for clothing, the impact of the epidemic has become more obvious. Recently, many well-known clothing companies have closed down. The most popular one is Brooks Brothers, which announced the closure. This clothing is known as "the special clothing for the presidential inauguration." The brand, 40 of the 45 presidents in the United States, all wore the brand’s suits at the inauguration, including Theodore Roosevelt, Kennedy, Ford, George Bush, and Clinton; the two US presidents in recent years, Trump and Obama is no exception. The brand fame even attracted former French President Chirac to buy shirts in stores in the United States.Brooks Brothers is only a representative one of the apparel companies, but it can also confirm from the side that this year's apparel market prospects are indeed worrying. If the piece of clothing doesn't work, then the dyeing plant's operation rate will naturally be difficult to increase.The block of the dyeing factory is blocked, indicating that the terminal demand cannot rise, and the trade is not ideal. What is the consequence of being pushed down from the bottom?The upstream collapsed one by one!Weaving manufacturers bear the bruntWeaving is already obvious. Manufacturers' inventory has soared to the highest level in recent years. According to the statistics of China Silk Capital, the inventory of grey cloth in Shengze area has risen to around 45 days, at a high level of nearly 4 years. At the same time, most grey cloths have significant price pressures on profits, and price losses are common when goods are thrown away. At present, it has entered the traditional low season, and it is more difficult for manufacturers to take orders. From the perspective of visiting the market, many weaving manufacturers are currently doing inventory. If the market continues to weaken, further reductions in construction will be a high probability event.Then there is the polyester manufacturerAt present, polyester manufacturers have been in a cumulative inventory cycle, and the inventory is at a high level since April. With the possibility of further decline in the start-up rate of downstream weaving manufacturers, it is difficult to make production and sales even, and even continuous polyester yarn promotional offers, There are very few markets with more than 100 production and sales. It can be seen that the low polyester yarn price has been difficult for the weaving manufacturers to pay for. This year is also the year when polyester production capacity is concentrated. Many devices under construction are planned to be launched this year, with more than 2.7 million tons put into production in the first half of the year and more in the second half. When the device continues to be put into production, inventory continues to rise, but profits continue to suffer losses, once the terminal is blocked, the possibility of polyester manufacturers crashing is very high.Then there are PTA manufacturersDue to the sluggish downstream polyester market, the current PTA market is also difficult to reverse, prices are outside the low level, and inventories are constantly accumulating. Generally speaking, this period of time in previous years was the most frequent period for PTA maintenance, but this year, it has been postponed more than once, and many sets of devices have been put into production. Recently, another production line of the Hengli 5# 2.5 million ton PTA plant, which was put into operation at the end of June, began trial production, and Zhongtai restarted 1.2 million tons. It is expected that July output will remain at an upper level of 4.3 million tons, an increase of more than 30 from June. 10,000 tons, the supply side of PTA will expand again. At the same time, the profit of PTA is also not ideal. Under the suppression of difficult processing costs, the cash flow has shrunk significantly, and it is even in a dilemma. If the demand cannot keep up in the later stage, it will face high risks.At present, it seems that weaving mills, polyester, and PTA are in a very saturated state and it is difficult to go to the warehouse. Once the most terminal link is blocked, the above links will face the risk of collapse. Especially polyester plants and PTA plants, with large production capacity and concentrated production capacity, will face greater risks than downstream links.......

- Polypropylene staple fiber has played such a big role in the construction of the project! [7/7/2020]
- Polypropylene staple fiber has played such a big role in the construction of the project!Polypropylene staple fiber is a secondary reinforcement added to prevent or reduce the initial plastic cracks of concrete. It is made of modified masterbatch added to polypropylene chips for blending, spinning and stretching. It is used for mortar concrete crack resistance Impervious engineering fibers. Its material is modified polypropylene.Polypropylene staple fiber undergoes special anti-static and anti-ultraviolet treatment to make the fiber evenly dispersed in the concrete and can exert its effect for a long time; the fiber trilobal cross-section increases the surface area of the fiber, and the fiber is chemically grafted and physically modified. The surface is rough and porous, which greatly improves the binding force between fiber and cement-based material. Adding to the concrete base material, it can be quickly and evenly mixed with the mortar concrete material.Due to the fine fibers and large specific surface area, there are about 45 fibers per 1 cubic centimeter of concrete, so it can form a chaotic support system inside the concrete, which can effectively control the early plastic shrinkage of concrete and cement mortar. The occurrence and development of non-structural cracks such as shrinkage effectively hinder the segregation of aggregates and the formation of settlement cracks, greatly improving the quality of concrete engineering and greatly reducing the cost of engineering maintenance.Therefore, polypropylene staple fiber has become an indispensable material in engineering construction!......
